Compounds that interact with kinases

ABSTRACT

A method of inhibiting or effecting the activity of protein kinase activity which comprises contacting a protein kinase with a compound of formula (I) being a derivative of a furanose or pyranose form of a monosaccharide, or a pharmaceutically acceptable salt thereof.

FIELD OF THE INVENTION

The invention is directed to classes of biologically active compounds that interact in a pharmaceutically significant manner with protein kinases, and particularly to provide compounds suitable for the treatment of disorders mediated by protein kinase activity. The invention is also directed to treatment of the above mentioned disorders. The invention is also directed to the preparation of novel compounds per se.

BACKGROUND OF THE INVENTION

The drug discovery landscape has been transformed by the genomics revolution. Advances in the understanding of biomolecular pathways and the roles they play in disease is generating vast numbers of targets for therapeutic intervention. Protein kinases now represent an extensive and important class of therapeutic targets.

Kinases are key components in almost all signal transduction pathways, modulating extracellular and intracellular signalling processes that mediate events such as cell growth and differentiation, metabolism and apoptosis. Kinases do this by catalysing the transfer of a phosphate group from ATP to protein substrates. The pivotal role of kinases is emphasized by the fact that kinases represent the third most populous domain in the proteome.

Kinases have been implicated in many diseases. Twenty percent of oncogenes code for tyrosine kinases. Kinases play pivotal roles in many leukemias, tumours and other proliferative disorders. Other states involving kinases include inflammatory disorders such as psoriasis, cardiovascular diseases such as restenosis, viral induced diseases such as Kaposi's sarcoma, circulatory diseases such as atherosclerosis and fibroproliferative diseases. Specific kinases are often implicated in particular disease states and therefore present themselves as potential targets for therapeutic intervention.

The kinase family includes serine/threonine kinases and tyrosine kinases, with the amino acid referring to the particular residue on a protein substrate that is phosphorylated. The tyrosine kinases can be further divided into receptor tyrosine kinases and non-receptor tyrosine kinases.

Considering the rate of generation and nature of the targets currently being deconvoluted by biologists, there is a need for the development of drug candidates, designed in a rational manner to purposely interact with selected targets, such as the kinases.

From a drug discovery perspective, carbohydrate pyranose and furanose rings and their derivatives are well suited as templates. Each sugar represents a three-dimensional scaffold to which a variety of substituents can be attached, usually via a scaffold hydroxyl group, although occasionally a scaffold carboxyl or amino group may be present for substitution. By varying the substituents, their relative position on the sugar scaffold, and the type of sugar to which the substituents are coupled, numerous highly diverse structures are obtainable. An important feature to note with carbohydrates, is that molecular diversity is achieved not only in the type of substituents, but also in the three dimensional presentation. The different stereoisomers of carbohydrates that occur naturally, offer the inherent structural advantage of providing alternative presentation of substituents. We have developed a system that allows the chemical synthesis of highly structurally and functionally diverse derivatised carbohydrate and tetrahydropyran structures, of both natural and unnatural origin. The diversity accessible is particularly augmented by the juxtaposition of both structural and functional aspects of the molecules.

A number of kinase inhibitors have appeared in the scientific literature to date. Many have entered human clinical trials and in two cases, Gleevac and Iressa, approval for the treatment of various tumours has been granted (Cohen, P., Nature Tev. Drug Discovery, 1, 309-316, 2002). The specificity of published kinase inhibitors varies widely and it is apparent from the study of Gleevac that specificity for a single kinase is not a prerequisite for the inhibitor becoming a useful drug, indeed the inhibition of more than one kinase may be an advantage for therapeutic intervention. Despite some promiscuity in the target kinase being acceptable, it is generally considered desirable to have good selectivity for the target kinase(s) over more general “housekeeping” kinases. Thus selectivity and inhibitor potency must be assessed on a case by case basis.

The level of inhibition in cell based assays also shows considerable variation from approximately 0.1 micromolar to over 100 micromolar as exemplified by the following table (a more detailed study can be found in: Davies et. al., Biochem. J., 351, 95-105, 2000; and Bain et. al., Biochem. J., 371, 199-204, 2003). It is frequently the case that the most potent inhibitor is not the most suitable inhibitor for therapeutic purposes.

SUMMARY OF THE INVENTION

Using the axioms of this drug discovery methodology, we synthesised several novel classes of chemotypes in an effort to develop drug candidates against kinase targets.

Kinases selected examples from the three different classes; serine/threonin kinase, tyrosine receptor kinase and tyrosine non-receptor kinase have been explored to determine the generality of the current invention. Compounds were tested within the industry standard concentration range described above and have revealed potent and selective inhibitors against each selected kinase target.

BEST MODE General Methods

General Method 1—Amide bond formation: To a solution of an acid in DMF (0.3 ml, 0.35 M, 1.0 equiv.) at room temperature was added a solution of HBTU in DMF (0.3 ml, 0.42 M, 1.2 equiv.) followed by DIPEA (2.5 equiv.). After 10 min., a solution of the desired amine in DMF (0.3 ml, 0.37 M, 1.05 equiv.) was added. The resulting solution was stirred at room temperature for 2.5 h, then diluted with DCM (8 ml) and washed with 10% citric acid (2×5 ml), saturated NaHCO₃ (2×5 ml), brine (5 ml) and water (5 ml). The solvent was removed in vacuo.

General Method 2—Ester Hydrolysis: A solution of the ester (0.1 mmoles) in THF (0.5 ml) was treated with a solution of lithium hydroxide in water (0.5 ml, 0.45 M, 2.1 equiv.). The resulting mixture was stirred at room temperature overnight, then evaporated to dryness under reduced pressure to provide the corresponding carboxylic acid as the lithium salt. The residue is redissolved in either ethyl acetate or dichloromethane and washed with a small quantity of 10% citric acid solution, followed by drying of the organic layer and removal of the solvents in vacuo to yield the desired carboxylic acid. In cognate experiments sodium hydroxide or potassium hydroxide has been substituted for lithium hydroxide to for the corresponding sodium or potassium salts in comparable yields. Methanol and dioxane have been substituted for THF as the reaction solvent with comparable results.

General Method 3a—Removal of acid labile protecting groups (Isopropylidene and BOC)—solution phase: The compound was dissolved in acetonitrile and treated with 90/10 trifluoroacetic acid-water (2 ml) and monitored by t.l.c for reaction completeness. Reaction times vary considerably from 15 minutes at RT to 6 hours at RT. When complete, the mixture was concentrated under reduced pressure and co-evaporating from acetonitrile. The crude products were resuspended in water-acetonitrile and lyophilised then purificatied by reverse phase C-18 HPLC using a solvent gradient of water/acetonitrile to afford the desired product as white solids. In cognate experiments, 50/50 trifluoroacetic acid—water has been used with similar efficiency.

General Method 3b—Removal of acid labile protecting groups (isopropylidene and BOC) and cleavage from resin—solid phase: The resin bound compound (approx. 200 mg of resin) was washed with DCM (2×2 mL) then treated with TFA/DCM 1:1 (1 mL) for 15 mins. The resin was filtered and washed with acetonitrile (1 ml) (filtrates collected). This procedure was repeated for a second cycle. The filtrates were evaporated under a stream of nitrogen. The residue was redissolved in water (1 ml) and agitated for 3 h. After this time, the solution was lyophilised to afford the crude products which were purified as described above.

General Method 4—removal of an Fmoc protecting group: The Fmoc protected compound on resin (12 g of resin, 0.7 mmol/g, 8.4 mmol) was washed with DMF (2×120 ml), then treated with 20% piperidine in DMF (120 ml) and shaken at r.t. for 30 min. The resin was drained and washed with DMF (2×120 ml). The reaction was repeated and the resin was drained, washed with DMF (2×120 ml), DCM (2×120 ml), MeOH (2×120 ml) and ether (2×120 ml), and dried in vacuo for 2 h.

General Method 5—coupling of fluoro-nitro-benzoic acid: Resin bound substrate was washed under N₂ with dry DCM (1×80 ml, 1×60 ml). To a solution of 4-fluoro-3-nitrobenzoic acid (9.3 g, FW 185.09, 50.2 mmol, 6 equiv.) in dry DCM (60 ml) and dry DMF (9 ml) at r.t. and under N₂ was added 1,3-diisopropylcarbodiimide (DIC, 3.9 ml, d 0.806, FW 126.20, 24.9 mmol, 3 equiv.). The solution was stirred for 10 min., then added to the resin followed by 4-(dimethylamino)pyridine (DMAP, 102 mg, FW 122.17, 0.83 mmol, 0.1 equiv.). The resin was then shaken at r.t. for 3 h, drained, washed with DMF (4×120 ml), DCM (3×120 ml) and ether (2×120 ml), and dried in vacuo overnight. The coupling procedure may be repeated in the event of a positive ninhydrin test.

General Method 6—nucleophillic aromatic displacement: Resin bound 3-nitro-4-fluoro-benzoate XI (200 mg, 0.14 mmol) was washed under N₂ with dry DMF (2 ml) or dry DMSO (2 ml), then treated with a solution of the nucleophile (0.42 mmol, 3 equiv.) and diisopropylamine (DIPEA, 0.146 ml, d 0.742, FW, 129.25, 0.84 mmol, 6 equiv.) in dry DMF (2 ml) or dry DMSO (2 ml) and shaken at r.t. o/n. The resin was drained and washed with DMF (3×2 25 ml) and DCM (3×2 ml). In the case of DMSO as solvent, the reaction was warmed to 60° C. The nucleophile may be any suitable primary or secondary aliphatic or aromatic amine, or a thiol. In an alternative experiment, the nucleophile was bound to the solid support and treated with an excess of ortho-fluoro-nitrobenzyl derivatives under similar conditions.

General Method 7—reduction of an aromatic nitro group: The resin bound substrate (0.14 mmol) was washed with DMF (2×2 ml) and then suspended in DMF (0.7 ml) to which was added a solution of SnCl₂.2H₂O in DMF (0.7 ml, 2 M, 1.40 mmol, 10 equiv.). The resin was shaken at r.t. o/n, then washed with DMF (5×2 ml), DCM (3×2 ml) and MeOH (5×2 ml).

General Method 8 preparation and reaction of an acid chloride: Resin bound substrate (0.14 mmol) was washed with DCM (2×2 ml) and then under N₂ with dry DCM (2×2 ml). A suspension of the of sugar-acid building blocks (0.42 mmol, 3 equiv.) in dry DCM (2 ml) was treated with triphosgene (42 mg, FW 296.75, 0.14 mmol, 1 equiv.) followed by collidine (0.159 ml, d 0.917, FW 121.18, 1.20 mmol, 8.6 equiv.). An effervescence was observed and a solution formed. After 1 min., this solution was added to the resin bound substrate and the resin was shaken at r.t. for 3 h. The resin was drained and washed with DCM (5×2 ml) and MeOH (3×2 ml).

General Method 9 cleavage of adenosine N-benzoyl group: The adenosine-containing products were treated with saturated ammonia in methanol (4 ml) at rt. o/n. The solvent was removed in vacuo and the product was again treated with sat NH₃ in MeOH at r.t. o/n. The solvent was removed in vacuo and compounds purified as described above. In an alternative procedure, 1M hydrazine hydrate in DMF was substituted for methanolic ammonia. The latter procedure is particularly useful for benzoate removal on solid support.

General Method 10—benzimidazole synthesis: Resin bound substrate (approx. 200 mg, 0.14 mmol) was treated with a solution of an aldehyde (5.0 equivalents) in N-methylpyrrolidine (NMP)(4 ml) and heated to 45-50° C. overnight. The resins were subsequently washed with DMF (3×4 mL), DCM (3×4 mL), MeOH (3×4 mL), ether (3×4 mL) and dried in vacuo overnight.

General Method 11—Cesium carboxylate coupling: The cesium salt of the Boc protected amino acid is made by dissolving the amino acid in methanol (5 ml/mmol) and water (0.5 ml/mmol) and adding an aqueous solution of 20% Cs₂CO₃ until pH 7 is reached. The solvent is removed in vacuo and the material is freeze-dried overnight to give a white powder. The resin is treated with the cesium salt (5 eq) in dry DMF (4 ml/g of resin) and stirred at 50° C. for 24 hours.

The resin is then drained and washed with THF/MeOH (1:3; ×3, DMF/MeOH (1:3; ×3), DCM/MeOH (1:3; ×3) and DCM.

General Method 13—Urea formation: In a gloved box, the resin is swelled in 10% DIPEA/DCM, a solution of triphosgene (2 eq in 1.2 ml of dry DCM) was added to the resin in two batches and shaken for 1 hour. The resin is washed with dry DCM (1 ml×2) and a solution of the amine (1.1 eq) and DIPEA (2.2 eq) in 1.5 ml of dry DCM was added and shaken for 30 minutes. The resin is drained and washed with DMF (×3), DCM (×3) and MeOH (×3) and dried.

General Method 14 base catalysed ring closure: The resin was treated with a solution of MeOH/NEt₃ (9:1; 2 ml) and heated to 60° C. overnight. The resin is drained (collecting the filtrate) and washed with MeOH, (1 ml), DCM (1 ml), MeOH (1 ml) and DCM (1 ml). The filtrates are combined and the solvent removed in vacuo. The process is then repeated.

General Method 15—Thiourea formation: Resin bound substrate was washed under N₂ with dry THF (3×30 mL) then thiocarbonyl diimidazole (2.49 g, 14 mmol) in dry THF (70 mL, conc=0.2M) was added and the resin was shaken at rt for 12 h. The resin was filtered, washed with THF (3×30 mL), DMF (2×30 mL), DCM (2×30 ml), DCM/MeOH (30 mL), MeOH (30 mL) and dried in vacuo.

General Method 16—S alkylation of an isothiourea: The reactions were performed in Bodhan Miniblocks. The resin bound thiourea compound resin(200 mg) was washed under N₂ with dry DMF (2×2 mL). Alkyl halide R¹X (0.7 mmol) in dry DMF (1 mL) was added followed by DIPEA (1.4 mmol) in dry DMF (1 mL). The resin was shaken at rt for 12 h, then washed with DMF (3×2 mL), DCM (3×2 mL), DCM/MeOH 1:1 (2×2 mL), MeOH (2×2 mL).

General Method 17—bromoacetylation: To bromoacetic acid (7.76 g) in dry DCM (40 mL) was added slowly DIC (4.4 mL) at 0° C. The solution was stirred at 0° C. for 30 mins. The solution was syringed out leaving the precipitated urea.

Resin bound substrate was washed under N₂ with dry DMF then swollen in dry DMF (1 mL). The bromoacetic anhydride solution in dry DCM (1 ml) was added and the resin was shaken at rt for 1 hrs. The resin was filtered, washed with dry DMF (3×3 mL) under N₂ (glove box) and dry DCM (2×3 mL). Excess DCM was drained applying positive pressure of N₂. The resin was carried through the next step immediately.

General Method 18—N-alkylation: Bromoacetylated resin produced by general method 17 is added to a sugar amine building block (5 eq) in DMF (1 mL). The resin was shaken at rt for 16 h then filtered, washed with DMF, DCM, DCM/MeOH and dried in vacuo.

General Method 19—Dichloro-Nitropyrimidine addition: The resin was swelled in NMP and a solution of 4,6-Dichloro-5-nitropyrimidine (5 eq) and DIPEA (10 eq) in NMP (1 ml/100 mg resin) was added and shaken at room temperature overnight (solution turned deep orange-red). The resin was drained under nitrogen and washed with dry DMF and dry DCM until filtrate is colourless and dried in vacuo.

General Method 20—Nitro reduction: The resin was swelled in DCM (1.5 ml/100 mg) and a solution of K₂CO₃ (10 eq) and Na₂S₂O₄ (8 eq) in H₂O (0.75 ml/100 mg) was added. Viologen (0.4 eq) was then added turning the solution deep blue. The resin was then shaken vigourously for 72 hours. The resin was then drained and washed with an aqueous solution of 1% AcOH, THF, DMF and DCM and dried in vacuo.

General Method 21—Aldehyde cyclisation: A solution of the aldehyde (5 eq) in NMP with 1% AcOH (800 μl/100 mg resin) was added to the dry resin in a test tube. The tube was sealed but allowed to vent with a needle in the top. The resin was heated at 100° C. overnight. The resin was filtered and washed with DMF, DCM and MeOH and dried in vacuo.

General Method 22—Acid Chloride Acylation:

Resin bound substrate was washed under N₂ with dry DCM then swollen in DIPEA (20 eq)/DCM (1 mL). A solution of acid chloride (10 eq) in DCM (1 ml) was added and the resin was shaken at rt for 24 h. The resin was washed with DMF, DMF/MeOH, DCM, DCM/MeOH, MeOH and dried in vacuo.

General Method 23—Reaction with the isocyanates and the resin cleavage: The resin was taken up in DCE and cooled to 0° C. followed by isocyanate (4 eq) addition. After 30 minutes, 10% TFA/DCM was added followed by shaking for 1 hour at room temperature. The resin was filtered and washed with DCM. The filtrate was concentrated under reduced pressure to afford the crude residue.

General Method 24—Biological Assays:

Compounds were tested in vitro as follows.

Recombinant protein kinases, which were expressed as fusion proteins in SF9 insect cells or E. coli, were used for all in vitro assays. The purity and identity of each kinase was checked by SDS-PAGE/silver staining and by western blot analysis with specific antibodies.

All kinase assays except for p38a (see below) were performed in 96-well micro-titre plates. The assay components included assay buffer, ATP, test compound, enzyme and substrate.

The assay for all enzymes (except for the PKC see below contained 60 mM HEPES-NaOH, pH 7.5, 3 mM MgCl₂, 3 mM MnCl₂, 3 μM Na-orthovanadate, 1 mM DTT, 0.1 μM [γ-³³P]-ATP (approx. 5×10⁵ cpm per well).

The assay for the PKCs contained 60 mM HEPES-NaOH, pH 7.5, 1 mM EDTA, 1.25 mM EGTA, 5 mM MgCl₂, 1.32 mM CaCl₂, 5 μg/ml Phosphatidylserine, 1 μg/ml 1.2 Dioleyl-glycerol, 1.2 mM DTT, 50 μg/ml PEG₂₀₀₀₀, 0.1 μM [γ-³³P]-ATP (approx. 5×10⁵ cpm per well).

Table below details the amounts of enzyme and substrate that were used per well:

The reaction was stopped with 50 μl of 2% (v/v) H₃PO₄, plates were aspirated and washed twice with 200 μl of H₂O or 0.9% (w/v) NaCl. Incorporation of ³³P₁ was determined with a microplate scintillation counter.

The mitogen-activated protein kinase p38a assays were done in a proprietary microassay NanoCarrier™ 2080 format. In these assays phosphorylation was detected by a phospho-substrate specific monoclonal antibody in an indirect competition assay. The degree of binding of the antibody to the phospho-substrate was measured by fluorescence polarization using 2D-FIDA anisotrophy. In these experiments the final concentration of the enzyme was 1.6 nM and the substrate was 2 μM.

All data is presented as residual activity, which is the activity of the enzyme in the presence of the stipulated concentration of inhibitor or compound. 100% activity is the maximum activity of the enzyme in the absence of any inhibitor or compouound.

In all experiments the Z′ value was calculated according to Zhang et al (J-H Zhang, T. D. Y Chung, K. R. Oldenburg (1999) Journal of Biomolecular Screening 4:67-73) using the standard deviations and mean values of the positive and negative controls. Z′=1−(3*Stdev _(neg)+3*Stdev _(pos))/(Mean_(pos)−Mean_(neg))

Only data where the Z′ value was >0.5 was used.
